Rules: Your successful path must include ≥1 reflection and ≥1 refraction before hitting the sensor. Drag to move; select an object for rotate/material/delete controls.

- Refraction: \(n_1 \sin i = n_2 \sin r\); critical angle \( \sin c = n_2/n_1 \) (from dense to less dense).
- Specular reflection: angle of incidence = angle of reflection.
- Optical materials: refractive index at visible wavelengths (~589 nm).
Tips
- Drag items to move them. Tap to select then rotate with buttons.
- Blocks bend light; choose their material in the Selected Object panel.
- Use mirrors to change direction; combine with blocks to reach the sensor.
- Press Test Ray to run the trace; if it hits the sensor, you must also answer a Snell check for the first interface used.
